EDWARD SEELEY, OF SGRANTON, PENNSYLVANIA.

IMPROVEMENT IN SPRING BED-BOTTOMS.

Specification forming part of Letters Patent No. 179,819, dated July 11 1876; application filed May 29, 1876.

To all whom it may concern Be it known that I, EDWARD SEELEY, of Scranton, in the county of Luzerne and State of Pennsylvania, have invented a new and Improved Spring Bed-Bottom; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this specification, in which my invention is represented by a perspective view.

My invention relates to spring bed-bottoms; and consists in'the details of construction hereinafter more fully set forth and particularly claimed.

In the drawing is represented a rectangular frame, composed of side pieces a a and end pieces b I). These are made of any suitable material, and of any suitable size and strength. The ends of b b are made to project, and are adapted to rest on ledges in the frame of the bedstead to support the structure. Over this frame is wound a wire, or its equivalent, which is attached at one end to the end piece and wound around the ends, passing over and under, with spaces of proper width between the strands, until the whole surface is covered from side to side. The end of the wire is then fastened to the end piece I) in the same manner as at the beginning. In this way I form two rows of wires, one above and the other below, stretched from end to end of the bedbottom, and extending from side to side. These two rows or. sets I spread and tighten by means of a truss or trusses, as represented in the drawing. These trusses may be made of two bars, a 0, connected by pins d d d, which are fixed in the upper bar 0, and pass loosely through the lower. Over them, before the lower bar is put into place, are slipped spiral springs e e e. The trusses thus constructed are passed in b6'tW( en the wires or sets of wires, then pressed toward the ends, and arranged vertically, and the wires thereby are put under any desired tension. They are kept under tension by the springs e e e, which also add their elasticity to the whole structure.

It is evident that the form of the frame may be changed, and that other forms of truss may be used without departing from the spirit of my invention.

I claim as my invention- 1. The bed-bottom composed of a frame over which a wire is wound to form an elastic support, as set forth. t

2. The bed-bottom composed of a frame over which a wire is wound to form an elastic bottom, in combination with trusses, by which the wires are separated and put under tension, as set forth. a

3. The described bed-bottom, composed of a frame, wires wound thereon, truss composed of the upper and lower bars, pins, and springs, all constructed and arranged as set forth.
